Zipper&#39;s pull hook structure having replaceable pull sheet

ABSTRACT

The present invention provides a zipper&#39;s pull hook structure having a replaceable pull sheet. The pull hook comprises a first ring portion, a second ring portion, a hook portion, and a resilient sheet portion, which are integrally formed. The first ring portion and the second ring portion are folded and stacked together. The hook portion is bent into a hook shape, and has an opening. The resilient sheet portion is situated at the opening of the hook portion. One end of the resilient sheet portion forms a free end. The opening is closed flexibly through the help of the resilient sheet portion. The hook portion can be hooked at a joint ring of a pull sheet. A zipper&#39;s pull hook having a replaceable pull sheet is thus formed.

FIELD OF THE INVENTION

[0001] The present invention relates to a zipper's pull hook structurehaving a replaceable pull sheet and, more particularly, to a zipper'spull hook structure capable of connecting a pull sheet and a zipper headbody so that the pull sheet can be replaced flexibly.

BACKGROUND OF THE INVENTION

[0002] As shown in FIG. 1, a prior art zipper head structure comprises azipper head body 10 and a pull sheet 11. The pull sheet 11 is connectedwith the zipper head body 10 by using a pull hook 12 so that the pullsheet 11 can be used to pull the zipper head for opening or closing azipper.

[0003] The pull hook 12 has a ring portion 13 and a hook portion 14. Thering portion 13 is connected with a pivotal seat 15 at the top of thezipper head body 10. The hook portion 14 is hooked with a joint ring 16of the pull sheet 11 so that the pull hook 12 can be connected betweenthe zipper head body 10 and the pull sheet 11.

[0004] The above pull hook 12 is hooked at the joint ring 16 of the pullsheet 11 via the hook portion 14. The hook portion 14 is originally ofpanel shape. When the hook portion 14 is to be hooked at the joint ring16 of the pull sheet 11, it is necessary to penetrate the hook portion14 into the joint ring 16 of the pull sheet 11 and then bend the hookportion 14 into a fixed ring shape so that the ring-shaped hook portion14 can be joined with the joint ring 16 of the pull sheet 11. After thehook portion 14 is bent into a ring shape, it will form fixed connectionwith the joint ring 16. It is unable to separate them so that the pullsheet 11 cannot be replaced. If the pull sheet 11 is damaged, the wholezipper head needs to be replaced.

[0005] Moreover, because the pull sheet 11 cannot be replaced, a usermust use the same pull sheet 11 for a long time, lacking novelty andvariability. This kind of design of the pull sheet 11 thus cannot meetthe requirement of today's fashionable people.

[0006] Accordingly, the above zipper head has inconvenience anddrawbacks in practical use. The present invention aims to resolve theproblems in the prior art.

SUMMARY OF THE INVENTION

[0007] The primary object of the present invention is to provide azipper's pull hook structure having a replaceable pull sheet, wherein ahook portion of the pull hook has an opening. The opening is providedwith resilient closing function by a resilient sheet portion. In orderto open the opening, it is only necessary to push a free end of theresilient sheet portion to swing inwards. The hook portion can thus beconnected with a joint ring in mobile way, and can be separated from thejoint ring so that the pull sheet can be easily replaced.

[0008] Another object of the present invention is to provide a zipper'spull hook structure having a replaceable pull sheet, whereby when thejoined pull sheet is damaged, the pull sheet can be separately replaced.It is not necessary to replace the whole zipper head, hence avoidingneedless waste.

[0009] Yet another object of the present invention is to provide azipper's pull hook structure having a replaceable pull sheet, whereinthe pull sheet can be replaced in mobile way. A user needs not to usethe same pull sheet for a long time, and can replace a pull sheet ofdifferent shape at any time, hence having better novelty and variabilityand conforming to the requirement of today's fashionable people.

[0010] To achieve the above objects, the present invention provides azipper's pull hook structure having a replaceable pull sheet. The pullhook comprises a first ring portion, a second ring portion, a hookportion, and a resilient sheet portion, which are integrally formed. Thefirst ring portion and the second ring portion are stacked together. Thehook portion is bent into a hook shape, and has an opening. The pullhook can be hooked at the pull sheet via the hook portion. The resilientsheet portion is at the opening of the hook portion. One end of theresilient sheet portion forms a free end. The opening is closed flexiblyby the resilient sheet portion. A zipper's pull hook structure having areplaceable pull sheet is thus formed.

[0011] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing, in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] As shown in FIG. 2, the present invention provides a zipper'spull hook structure having a replaceable pull sheet. The pull hook 20 isoriginally of panel shape before being bent. The pull hook 20 comprisesa first ring portion 21, a second ring portion 22, a hook portion 23,and a resilient sheet portion 24, which are integrally formed. The shapeof the first ring portion 21 corresponds to that of the second ringportion 22. The first and second ring portions 21 and 22 have throughholes 26 and 25, respectively. The hook portion 23 and the resilientsheet portion 25 are connected to one end of the first and second ringportions 21 and 22, respectively.

[0020] As shown in FIGS. 3, 4, and 5, a joint portion 27 is connectedbetween the first and second ring portions 21 and 22. The first andsecond ring portions 21 and 22 can be folded at the joint portion 27 sothat they can be stacked together. The hook portion 23 can be bent intoa U-shaped hook by punching. The hook portion 23 has an opening 29. Theresilient sheet portion 24 is bent to show a slanting shape, and issituated at the opening 29 of the hook portion 23. One end of theresilient sheet portion 24 forms a free end, and can abut against oneend of the hook portion 23. The opening 29 is closed flexibly by theresilient sheet portion 24. The resilient sheet portion 24 can also bebent to form an arc portion 28 to increase resiliency of the resilientsheet portion 24. The cross section of the hook portion 23 can be madeto form an arc shape by punching to have reinforcing function. Azipper's pull hook structure having a replaceable pull sheet of thepresent invention is thus formed.

[0021] As shown in FIG. 6, the pull hook 20 of the present invention canbe connected at a pivotal seat 31 at the top of a zipper head body 30 byusing the two ring portions 21 and 22. The hook portion 23 is hookedwith the joint ring 41 of the pull sheet 40. The resilient sheet portion24 can provide retaining function for the joint ring 41 to avoid thesituation that the joint ring 41 leaves the hook portion 23 from theopening 29. The pull hook 20 can thus be connected between the zipperhead body 30 and the pull sheet 40 so that the pull sheet 40 can be usedto pull the zipper head for opening or closing a zipper.

[0022] As shown in FIG. 7, the hook portion 23 of the pull hook 20 ofthe present invention has an opening 29, and the resilient sheet portion24 provides flexible closing function for the opening 20. In order toopen the opening 29, it is only necessary to push the free end of theresilient sheet portion 24 to swing inwards so that the joint ring 41 ofthe pull sheet 40 can leave from the hook portion 23 of the pull hook20. Because the hook portion 23 is connected with the joint ring 41 inmobile way and can be separated from the joint ring 41 after being bent,the pull sheet 40 can be replaced. If the pull sheet 40 is damaged, itcan be separately replaced. It is not necessary to replace the wholezipper head, hence avoiding needless waste.

[0023] Furthermore, the pull sheet 40 of the present invention can bereplaced in mobile way. A user needs not to use the same pull sheet 40for a long time, and can replace a pull sheet 40 of different shape atany time, hence having better novelty and variability and conforming tothe requirement of today's fashionable people.
